Way! I didn't know that, I use table.insert(a, item) everwhere, how
much is the difference?

Not in favor of deep copy, but I suppose a C implementation that
copies the whole hashtable should way effectiver than
for k, v in pairs(table) do
   newtable[k] = v
end
shouldn't it?

And I do this occassionaly, but maybe you just proven me, that I'm not
actually using the effectivst things?
